Hi,

Given that you're facing a linker and not a compiler error, it should be
just choking on the name that the linker needs to resolve to an export from
a library. One possible problem could be the way the compiler is storing
the name for the linker. If you are compiling a .cpp file, it could be
possible that the compiler is decorating the function name (C++). Check by
looking at the linker error message and compare it with the output for the
function from the following:

dumpbin msvcrt.lib /exports (it should be _sqrt)

If you see something like ?sqrt@@YGE (I made this up) in the linker error,
then this is the problem.

To get around it, get the compiler to assume C style function names.

extern "C" {
#include <math.h>
}

Hope this provides some hints,
